Der Himmel dacht auf Anhalts Ruhm und Glück, BWV 66a
Der Himmel dacht auf Anhalts Ruhm und Glück (Since heaven cared for Anhalt's fame and bliss), BWV 66.1, BWV 66a, is a congratulatory cantata by Johann Sebastian Bach. The work was first performed in Köthen on 10 December 1718. The music has been lost apart from a fragment, but Bach appears to have recycled some of his material in other works, allowing for the cantata's partial reconstruction.
